Tiny BMS s516 - 150A/750A

Features

• Very small dimensions.
• Flexibility: 4 to 16 cells of any kind, including Li-ion, LiPo, LiFePO4, Li-Titanate and Li-sulfur chemistries
• Current measurement and SOC calculation.
• Firmware updates, new feature releases and improvements for free.
• Bluetooth connection (good for USB replacement).
• Event logs and live data view: easy to debug the system, check what happened and when.
• External contactor support for charger and load.
• External current sensor support up to 750A.
• Faster balancing due to "early balancing", which saves charging time.
• Ignition/enable input. BMS will switch off the output and go to low power mode when no signal on certain pin (if enabled).
• Temperature measurement in multiple points of the battery - for safety, to prevent overheating and charging in cold.

Specifications

• Series cells: 4 to 16 (6 to 16 for LTO)
• Cell voltage: 0.80 to 4.50 V
• Cell balancing: 150 mA, dissipative
